I haven't really noticed a difference when taking it, even combined with Pycnogenol and Citrulline. I read that as men get older, they are less efficient at converting arginine in this way, so perhaps that is why I don't see much effect.
I do get noticeably hornier and generally a better flaccid hang if i drink beet juice, though, which also boosts Nitric Oxide but via different mechanisms.
